WebFactorise 2x3 –3x2 –17x+30 Solution Let p(x) =2x3 –3x2 –17x+30 Constant term of p (x) = 30 ∴ Factors of 30 are ±1,±2,±3,±5,±6,±10,±15,±30 By trial, we find that p (2) = 0, so (x – 2) is a factor of p (x). [∵2(2)3−3(2)2−17(2)+30 =16−12−34+30= 0] Now, we see that 2x3 –3x2 –17x+30 = (x−2)(2x2+x−15) Web(Remember that this is how we solved quadratics by factoring: We'd find the two factors, set each of the factors equal to zero, and solve. Here, we're working backwards from zeroes to factors.) Using this information, I'll do the synthetic division with x = 4 as the test zero on the left: cmc share dividends https://bioforcene.com
